Abstract: 1375948 Thermally insulating panel BALSA ECUADOR LUMBER CORP 3 Feb 1972 [10 Feb 1971 10 Nov 1971] 5112/72 Heading B5N [Also in Divisions F2 and F4] A thermal insulation panel comprises at least one facing sheet bonded to at least one layer formed from balsa wood beams and another insulating material of similar thermal conductivity substantially filling the spaces between the beams. Several layers L 1 , L 2 , L 3  (Fig. 2), may be superposed and the axes of the beams in one layer may be displaced from the axes of the beams in an adjacent layer. The other material may be in the form of slabs or bags of expanded material: foamed polyurethane, polystyrene, P.V.C. or glass, expanded mineral insulation, e.g. perlite or vermiculite, fibreboard, fibreglass insulation, rockwool, hairfelt and cork being referred to. The facing sheet, which may form the inner surface of a liquid storage tank may be formed of plywood, aluminium, high pressure phenolic polymers, steel, a flexible open mesh screen of glass fibres, a polyurethane film or paper and may be bonded to the core with an epoxy or urethane adhesive. The slabs may be pre-compressed before assembly so that as the panels are cooled gaps do not form between the beams and the slabs. The gaps between the edges of adjacent panels which may be dove-tailed or mitred may be filled with flexible insulation. In Fig. 9, the panel is composed of fire-retardant plywood facing sheets 38, 44 and a core of two layers of balsa beams B and insulating slabs F separated by a plywood sheet 40, the upper and lower parts being offset as shown to provide for interfitting.

Title: Through hole tapping tool - has helical flutes of variable depth for swarf removal and breaking up
Inventor: ISHIBASHI SHIGEO
IPC: B23G5/06
Filed: 1973-06-22
Abstract: The tapping section has helical flutes for swarf removal. The relatively small angle helix of the flutes runs in opposite direction to the screw thread helix. The flutes are very deep in the starting part of the tapping tool and the flutes become relatively shallow gradually towards the shank end. This tapping tool is for tapping through holes but is not as suitable for tapping blind holes because the swarf is directed toward the tapping tool feed. Higher tapping speeds can be used with this tapping tool and the torque required on tapping is about one quarter less than that required for tapping tools for straight flutes.

Title: Expanding plug for wall bore - is cross shape vane opened against hole sides by bolt tension
Inventor: RIEDEL JOSEF
IPC: F16B13/04
Filed: 1973-07-27
Abstract: The plug casing encloses a screw with a nut on the inner end. The nut holds the straddling component which consists of vanes projecting radially beyond the casing. The vanes have a cutting front edge and their curved rear edges thrust against the segments of the casing. The bolt pulls the vaned section against a hollow sleeve which pushes the arms of the vanes away from the hole open end, and forces them outward against the other part of the vane web. A setting filler material is used to assist in holding the plug in.
